Moreover, and as in the case of IPF LFs, mouse primary LFs isolated post-BLM administration presented with increased Tks5, Col1a1 and Mmp9 expression (Supplementary Fig. 7l–n respectively), exhibiting prominent podosome rosettes in the absence of any stimulation (Supplementary Fig. 7o–p). Here, COL1A1 is linked to idiopathic pulmonary fibrosis.
